I built and launched Capo, a Chrome Web Store extension that helps musicians practice songs by adjusting pitch, playback speed, and volume.
At Elyra, I manage Capo from planning and implementation through testing, release, and ongoing improvements. I create interactive TypeScript and React interfaces, integrate audio-processing features, and focus product decisions on a better music-learning experience.
